Nonlinearity-induced Topological Phase Transitions in One-dimensional Systems with Chiral Symmetry: A Real-Space Treatment
Liu Bi Tao, Shilpi Roy, Jiangbin Gong
Nonlinearity can induce topological phase transitions in periodic systems. It is hence of considerable interest to examine if such transitions persist in the absence of translation…
Aperiodic Dissipation as a Mechanism for Steady-State Localization
Shilpi Roy, Jiangbin Gong
Dissipation is traditionally regarded as a disruptive factor in quantum systems because it often leads to decoherence and delocalization. However, recent insights into engineered d…
Quasiperiodic disorder induced critical phases in a periodically driven dimerized -wave Kitaev chain
Koustav Roy, Shilpi Roy, Saurabh Basu
The interplay of topology and disorder in non-equilibrium quantum systems is an intriguing subject. Here, we look for a suitable platform that enables an in-depth exploration of th…
Ergodicity-breaking phase diagram and fractal dimensions in long-range models with generically correlated disorder
Shilpi Roy, Saurabh Basu, Ivan M. Khaymovich
Models with correlated disorders are rather common in physics. In some of them, like the Aubry-André (AA) model, the localization phase diagram can be found from the (self)duality…
Critical and Topological Phases of Dimerized Kitaev Chain in Presence of Quasiperiodic Potential
Shilpi Roy, Sk Noor Nabi, Saurabh Basu
We investigate localization and topological properties of a dimerized Kitaev chain with p-wave superconducting correlations and a quasiperiodically modulated chemical potential. Wi…
Phase Properties of Interacting Bosons in Presence of Quasiperiodic and Random Disorder
Sk Noor Nabi, Shilpi Roy, Saurabh Basu
Motivated by two different types of disorder that occur in quantum systems with ubiquity, namely, the random and the quasiperiodic (QP) disorder, we have performed a systematic com…
Critical analysis of the re-entrant localization transition in a one-dimensional dimerized quasiperiodic lattice
Shilpi Roy, Sourav Chattopadhyay, Tapan Mishra +1
A re-entrant localization transition has been predicted recently in a one-dimensional quasiperiodic lattice with dimerized hopping between the nearest-neighbour sites (Phys. Rev. L…
Reentrant Localization Transition in a Quasiperiodic Chain
Shilpi Roy, Tapan Mishra, B. Tanatar +1
Systems with quasiperiodic disorder are known to exhibit localization transition in low dimension. After a critical strength of disorder all the states of the system become localiz…
